Devils Lake History on one map chip - For Lowrance Touch Screens only

Three Devils Lake map cards in one  1990 - 1980IR - 1949 and the Color survey.   This map card will only work with Lowrance Touch Screen units.   Works in all: HDS Pro, Touch Gen 2-3-Carbon-Live Warning: At this time the map chips have issues with  being very dark on Elite FS units.  They work great in all other touch screens. Comes on a micro SD card with SD adapter.   Not suggested for Gen 1 or Gen 2 keypads.  Will work with Gen 2 Touch Military point 1990   Military point 1980 Infrared Military point 1949   .Military point color survey Testimonial I just wanted to let you guys know how happy I am with your lowrance sd  chip maps.  They work incredible on my lowrance carbon 16 and also my prior gen 3's.    I bought the 3 sd card set with the 1949, 1980 and 1990 maps. How it overlays the satellite imagery from back then in such good clarity is a game changer for finding areas that will hold big walleyes.      We finished high in the last 4 Cabela's MWC tournaments at devil's lake f
